Linked Data & RDF: New Frontiers in Metadata and Access - Amigos Online ConferenceApril 23, 2015

What is Linked Data?

“Linked Data describes a method of publishing structured data, so that it can be interlinked

and become more useful. It builds upon standard web technologies, such as HTTP and URIs - but rather than using them to serve web pages for

human readers, it extends them to share information in a way that can be read

automatically by computers.”

http://en.wikipedia.org/wiki/Linked_Data

“Just as the traditional document Web can be crawled by following hypertext links, the Web of Data can be crawled by following RDF links. Working on the crawled data, search engines can provide sophisticated query capabilities... Because the query results themselves are structured data, not just links to HTML pages, they can be immediately processed, thus enabling a new class of applications based on the Web of Data.”

Chris Bizer, Richard Cyganiak, and Tom Heath

Web Visibility

“When my community searches the web for something we have, we better show up as an option.”

There’s a lot more information out there

And it will be explored more aggressively

Libraries and Privacy

“Librarians feel a professional responsibility to protect the right to search for information free from surveillance. Privacy has long been the cornerstone of library services in America.Why? Because the freedom to read and receive ideas anonymously is at the heart of individual liberty in a democracy. Librarians defend that freedom every day.Libraries are information hubs for their communities. They are also natural centers for learning and talking about information issues… including privacy.”

Libraries, Linked Data, Privacy

and Vendors

“Libraries no longer own much of the content they provide to users; rather it is subscribed to from a variety of vendors. Not only does that mean that vendors will have to make their data available in linked data formats for improvements to federated search to happen, but a mix of licensed and free content in a linked data environment would be extremely difficult to manage.”

Privacy Preference Ontology

Allows users to define “fine-grained privacy

preferences for restricting (or granting) access” to their information

Owen Sacco and Alexandre Passant

A Privacy Preference Ontology (PPO) for Linked Data http://events.linkeddata.org/ldow2011/papers/ldow2011-paper01-sacco.pdf

Ontology = Vocabulary

“Vocabularies are used to classify the terms

that can be used in a particular application, characterize possible relationships, and define possible constraints on using those terms.”
